PATENT JULIUS A. SPENCER, OF DWIGHT, ILLINOIS.

HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 359,475, dated March 15, 1837.

Application filed December 4, 18H6. Serial No. 220,738. (No model.)

To all whom it may concern: y

Be it known that I, JULIUs A. SPENCER, a citizen of the United States of America, residing at Dwight, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Horse-Powers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain vimprovements in horse-powers for operating the togglejoint of -a baling-press, the construction and operation of which are fully set forth and explained in the following specification and claims, reference being had to the accompanying drawings, and the letters and figures of reference thereon,making a part of this speciiication, in which- Figure lis a top plan view of the horsepower as it would appear connected with a toggle-joint baling-press, having parts broken away to more clearly show its working parts. Fig. 2 is a central vertical section of the cam attached to the sweep of the power. Fig. Sis atop plan view of the sweep-cam detached from the remaining parts of the power. Fig. 4. is a side elevation of the power,having parts broken away to see its interior parts, and showing itplaced with relation to a togglejoint baling-press. Fig. 5 is a perspective of one of the slides of the power to show its form andthe manner of attaching it to the chain for opening the toggle of the baling-press to fold said toggle, and Fig. 6 is a perspective View of one of the slides of the power for operating in the peripheral groove of the sweepcam to which the chain for straightening the toggle of the baling-press is attached.

Referring tothe drawings, D D are the two side beams of the frame of the power,arranged so their front ends,near the hailing-press Rare near together and secured to the shoeS, and so thetwo chains C G' may/pass between them. The rear extending ends of said beams diverge from each other, and are connected by means ofthe cross-beams D D2 D5 D6 Q Q', as shown in Figs. 1 and 4. i t is a circle arranged on the power concentrically with the shaft A of cam J for 5o strengthening the frame and for att-aching parts of the power to.

J is a cam secured to upright shaft A, to

which the sweep A2 is attached through the medium of hub A', which shaft is stepped in beam Q and boxed to beam Q.

The power is intended to connect with the baling-press I by means of the box B,forming a throat for the chains C C to operate in, and by means of braces E E and brace-chain G, as shown in Fig. 1,0r in any other suitable man- Ilel.

The cam J is elongated, as shown in Figs. l and 3, for the purpose hereinafter stated, and is provided with a peripheral groove T- shaped in cross-section, as shown at N, Fig. 2, for the reception of thc slide H, as shown in said figure, its `lugs H standing vertically therein Within the upturned and depending flanges thereof, and its body portion extending outward and curved in form to permit it to pass around the short curves of the can J.

J is a removable plate, covering an opening in the cam J, so said slide II can be readily inserted in said groove. Chain C, having the central link d, connects said slide H with the elbow of the toggle T T of the baling-press.

S2 is a slide arranged on the guide S. Chain C', having the central link, d, connects said slide with cam Y on the lower end of the toggle T of the baling-press, as shown in Fig. 4.

aand ct are spring-catches arranged in guideways in the upper side of cam J and arm J2, respectively, in the position shown in Figs. 1, 2, and 3. Said arm is secured to cam J, and is for the purpose of reaching from said cam J to support said catch et' so it will engage slide S2, as shown in Fig. l, catch a being arranged so it will engage with slide H.

y. Z and Z are stationary cams secured to the power-frame, as shown in Fig. l, and arefor the purpose of engaging, respectively, the friction-rollers V and V', studded on said springcatches, for the purpose of .withdrawing them lfrom their engagement, respectively, with the slides H and S2. The arm J2, on which catch a is arranged,-holds said catch beyond cam Z, so it will not engage therewith, and roller o of catch a, being nearer shaft A, will not engage with cam Z. The chain C winds and unwinds from the periphery of -cam J, as shown in Fig. l, and the extending flange L cf said cam (shown in Fig.

ICO

2) guides said chain and causes it to wind up on said cam, as shown, so one side of its horizontal links enter said groove and the vertical links lie against thc periphery of said cam on either side of its groove, as shown in Fig. 2.

It is intended to attach a team tothe sweep A2 and cause them to travel in one direction continuously, as indicated by the arrow in Fig. l, which will rotate cam J continuously in one direction to reciprocate the two chains CC'to fold and straighten the toggle T. \Vhen the said cam rotates, the spring-catch ay will engage with slide H by means of being held out so it will be presented in groove N by spring 3l, as shown in Fig. 2, and carry said slide around with cam J, so the chain C will be wound on the cam J, as shown in Fig. 1, which will straighten the toggle T to reciprocate a follower that may be attached to it for compressing the bale. \Vlien the toggle is thus straightened, the cam J has rotated so the friction-roller V on catch c will engage with stationary cam Z and cause said catch to be withdrawn from its contact with slide H, so said slide may be drawn backward by the toggle as it is folded by the opposite chain. ln Fig. l catch c is shown as just having been thus released from slide H, and said slide H is in the act of moving back ward in the groove in the periphery of said cam. Immediately after said slide H is thus released catch c cngages with slide S2 on guide S, as shown in Fig. l, and moves it along on said guide, while slide H moves backward, causing chain C to elevate the `joint of said toggle, as shown in Fig. 4, and when that is accomplished frictionroller V, studded on catch c', will engage with stationary cam Z and cause catch a to be disengaged from slide S2, so it can return, when the movement of the chains is reversed, by means of catch a again engaging slide H, so that a continuous rotary motion of cam J will cause said chains to be reeiproeated, as stated, and the toggle to be folded and straightened.

The parts are so arranged that a short interval of time will elapse between the folding and straightening of the toggle to permit the bale-chamber to be fed. As more power is necessary at first to start the folding of the toggle than when partly folded,the cam Y, attached to the lower part of one of the togglearms to which chain C attaches, is set eccentrically with its axis, so that the chain has greater' leverage at the commencement of said operation, and so the draft on said chain is equalized by the form of said cam. The form of cam J is such that the increased power required to straighten the toggle as the said toggle is nearing its point of straightening and the bale within the baling-press chamber is becoming more compact is obtained by chain C being at that time wound on cam J at its side nearest shaft A, which equalizes the draft of sweep A2 by the increased leverage thus gained.

In connecting the chains C and C with the toggle T they pass, respectively, under pulleys R R', which are arranged in the frame of the baling-press, as shown in Fig. 4, in such manner that chain C, when operated, will pull directly down on the elbow of the toggle T, and when chain C is operated will pull down and backward one ccentrie cam Y of the said toggle, and thus each chain will alternately operate said toggle, as stated.

There are instances when the power is in operation working the toggle of a baling-press, when elastic material is being baled, that the toggle will be caused to fold quickly immedi ately al'ter being started to fold byy means of 8o the elastic pressure against the follower ofthe baling-press to which the toggle is attached, and will in such instances draw quickly on chain C, and thus canse slide H to rapidly move backward in the peripheral groove of cam J; and to prevent a sudden jerk of said chain on cam J at such times chain K (shown in Fig. l) is used, connecting chain C with crossbeam D2 ofthe power, and it is of proper length to arrest the motions of chain G when the slide H has completed its backward circuit, and will lie slack, as shown in said figure, when said chain is winding on cam J. ln addition to giving general strength to the power-frame, the circle t forms a track upon which wheel W' ol' sweep A2 travels, as shown in Fig. 4, and thereby supports the sweep on its circuit, thus releasing shaft A from side draft from the weight of said sweep.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is as follows, to wit:
